With guided test setups and automated measurements on drives that produce reliable, repeatable test results.<\/h2>\n<p>The Fluke MDA 550 Motor Drive Analyzer saves you time. You no longer need to set up complex measurements and motor drive troubleshooting becomes much easier. Simply select a test and the step-by-step guided measurements show you where to make voltage and current connections. In addition, preset measurement profiles ensure that you record all the data you need for each critical part of the motor drive, from input to output, the DC bus and the motor itself. From simple to advanced measurements, the MDA-550 lets you handle it all. And with a built-in report generator, you can produce reliable before\/after reports quickly and easily.<\/p>\n<p>The MDA-550 is the ideal portable instrument for analysing motor drives. It helps you detect and fix common inverter motor drive problems.<\/p>\n<ul>\n<li><strong>Measure key parameters for motor drives<\/strong>\u00a0such as voltage, current, DC bus voltage level and AC ripple, voltage and current unbalance and harmonics, voltage modulation and voltage discharges through the motor shaft.<\/li>\n<li><strong>Perform comprehensive measurements of harmonics<\/strong>\u00a0to identify the effects of low and high harmonics on your electrical system.<\/li>\n<li><strong>Perform guided measurements<\/strong>\u00a0to the motor drive input, DC bus, drive output, motor input and motor shaft with graphic, step-by-step wiring diagrams for voltage and current.<\/li>\n<li><strong>Use a simplified measurement setup<\/strong>\u00a0with preset measurement profiles to automatically trigger data collection based on the selected measurement procedure.<\/li>\n<li><strong>Create reports quickly and easily<\/strong>\u00a0which are perfect for documenting troubleshooting and collaborating with others.<\/li>\n<li><strong>Measure additional electrical parameters<\/strong>\u00a0with a full-fledged 500 MHz oscilloscope, metering and recording function for a complete range of electrical and electronic measurements on industrial systems.<\/li>\n<\/ul>\n<h2>The Fluke MDA-550 Motor Drive Analyzer uses guided test measurements to make analysis easier than ever<\/h2>\n<h3>Drive input<\/h3>\n<p>Measure the input voltage and current to quickly see if values are within acceptable limits by comparing the rated voltage of the drive with the actual supply voltage. Then check the input current to determine whether the current does not exceed the maximum value and the conductors are sufficiently sized. You can also check whether the harmonic distortion is within acceptable levels by visually checking the shape of the waveform or by viewing the harmonic spectrum screen, which shows both the total harmonic distortion and the individual harmonics.<\/p>\n<h3>Voltage and current unbalance<\/h3>\n<p>Check voltage unbalance at the inputs to make sure phase unbalance is not too high (&gt; 6-8%) and that phase rotation is correct. You can also check for current unbalance, as excessive unbalance may indicate a problem with the drive rectifier.<\/p>\n<h3>Comprehensive measurements of harmonics<\/h3>\n<p>Excessive harmonics are a threat not only to your rotating machinery but also to other equipment connected to the electrical system. With the MDA-550, you can look for the harmonics of the motor drive but also discover the possible effects of the inverter's switching electronics. The MDA-550 has three ranges for harmonics, from the 1st to the 51st harmonic, from 1 to 9 kHz and from 9 kHz to 150 kHz, so you can detect any problem related to harmonic contamination.<\/p>\n<h3>DC bus<\/h3>\n<p>In a motor drive, converting AC to DC in the drive is critical, as the correct voltage and adequate smoothing with low ripple is needed for the best performance of the drive. A high ripple voltage can be an indication of faulty capacitors or incorrect measurement of the connected motor. The record function can be used to monitor the performance of the DC bus dynamically in operating mode while a load is on.<\/p>\n<h3>Drive output<\/h3>\n<p>Check the output of the drive in terms of both voltage-to-frequency (V\/F) ratio and voltage modulation. At high readings of the V\/F ratio, the motor may overheat. At low readings of the V\/F ratio, the connected motor may not be able to deliver the required torque for the load to adequately perform the intended process.<\/p>\n<h3>Voltage modulation<\/h3>\n<p>Measurements of the pulse-width modulated signal are used to check for high voltage spikes that can damage the insulation of motor windings. The rise time or steepness of pulses is indicated by the dV\/dt value (the rate of voltage change over time). This should be compared with the specified insulation of the motor. The measurements can also be used to measure the switching frequency to determine if there is a possible problem with electronic circuitry, or with grounding, where the signal rises and falls.<\/p>\n<h3>Motor input<\/h3>\n<p>Ensuring the voltage supply to the motor input is essential, and the choice of cabling from the drive to the motor is critical. An incorrect choice of cabling can lead to damage to both the drive and motor due to excessive reflected voltage spikes. It is important to check that the current at the connections is within the motor specification, as overcurrent can lead to overheating of the motor, which can shorten the life of the stator insulation and therefore cause premature motor failure.<\/p>\n<h3>Motor shaft voltage<\/h3>\n<p>Voltage pulses from a frequency-controlled drive can be induced by the stator of an electric motor into the rotor of the motor, leading to an electrical voltage in the rotor shaft. If this rotor shaft voltage is higher than the insulating capacity of the bearing grease, arcing can occur, leading to pitting and grooving in the motor bearing raceway: damage that can cause a motor to fail prematurely. The MDA-550 comes with carbon brush measuring pins that easily detect the presence of destructive spark currents, while the impulse amplitude and event count allow you to take action before failure occurs. By using this accessory, you can detect potential damage without investing in expensive permanently installed solutions.<\/p>\n<h3>Step-by-step guided measurements ensure you have the data you need, when you need it<\/h3>\n<p>The MDA-550 is designed to help you quickly and easily test and troubleshoot typical problems on three-phase and single-phase inverter motor drives. Thanks to the on-screen information and step-by-step guidance, you can easily configure the analyser and take measurements on the drive to quickly make better maintenance decisions. From the power supply to the installed motor, the MDA-550 provides the measurement capabilities for the fastest troubleshooting of motor drives.<\/p>\n<\/div>\n<div id=\"ig-overview-flexslider\" class=\"ig-overview-flexslider\">\n<div class=\"flex-viewport\">\n<ul class=\"slides\">\n<li class=\"flex-active-slide\" data-thumb=\"h2\"><picture><source srcset=\"https:\/\/dam-assets.fluke.com\/s3fs-public\/MDA1.png\" media=\"(min-width: 1280px)\" data-original-src=\"https:\/\/dam-assets.fluke.com\/s3fs-public\/MDA1.png\" \/><source srcset=\"https:\/\/dam-assets.fluke.com\/s3fs-public\/MDA1.png\" media=\"(min-width: 1033px) and (max-width: 1279px)\" data-original-src=\"https:\/\/dam-assets.fluke.com\/s3fs-public\/MDA1.png\" \/><source srcset=\"https:\/\/dam-assets.fluke.com\/s3fs-public\/MDA1.png\" media=\"(min-width: 768px) and (max-width: 1032px)\" data-original-src=\"https:\/\/dam-assets.fluke.com\/s3fs-public\/MDA1.png\" \/><source srcset=\"https:\/\/dam-assets.fluke.com\/s3fs-public\/MDA1.png\" media=\"(max-width: 767px)\" data-original-src=\"https:\/\/dam-assets.fluke.com\/s3fs-public\/MDA1.png\" \/><img loading=\"lazy\" decoding=\"async\" class=\"lazyloadhot-trash lazyloaded\" title=\"Drive input step-by-step guided measurement connections\" draggable=\"false\" src=\"https:\/\/dam-assets.fluke.com\/s3fs-public\/MDA1.png\" alt=\"Drive input step-by-step guided measurement connections\" width=\"643\" height=\"440\" \/><\/picture>\n<p class=\"flex-caption-left\">Drive input step-by-step guided measurement connections<\/p>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<div class=\"djc_item_info\">\n<div class=\"djc_producer_info\"><small>Producer: Fluke<\/small><\/div>\n<\/div>\n<div class=\"djc_introtext\">\n<h2 class=\"features-title\">Key features<\/h2>\n<div id=\"keyfeature_content\">\n<ul>\n<li>Guided tests with graphical, step-by-step connection diagrams<\/li>\n<li>Preset measurement profiles reduce set-up complexity<\/li>\n<li>Built-in functions for writing reports<\/li>\n<li>Easily produce fault-finding reports of the situation before and after the event<\/li>\n<\/ul>\n<\/div>\n<\/div>","protected":false},"featured_media":5314,"template":"","meta":[],"product_brand":[],"product_cat":[61,62],"product_tag":[311],"class_list":["post-5313","product","type-product","status-publish","has-post-thumbnail","product_cat-power-en-pq-meters","product_cat-scopemeters1614240348","product_tag-elektrisch","first","instock","shipping-taxable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 -
